For technical reference on water and sewer terminology,
our 90-term glossary is the most complete resource on the site — covering DTC numbers, materials, methods, fittings, authorities, and site conditions. To understand how we estimate, see
our method or the discipline pages:
water,
sewer,
pump stations,
stormwater,
variations. For the engineering experience behind the work,
our About page covers it. For common questions about how we work, see
our FAQs. For a rough cost estimate before sending the drawings, try
