PROVISIONAL SPECIFICATION.
Improvements in Sewage Disposal Works for Towns, Villages, and
the like Draining into Tidal Waters.
EDWARD WILLIAM IVES of 2 Strand Derby in the County of Derby Civil
Engineer do hereby declare the nature of this invention to be as follows:-
The object of my invention is to purify foul or waste waters or sewage at all
states of the tides without letting the tidal waters back the sewage or waste waters
or sewage gases into the sewers and for this purpose I combine what is known as
an upward flow precipitating tank with a storage tank the latter having an effluent
overflow weir together with two tidal valves and an effluent outlet well one of the
tidal valves being level with the invert of sewer and effluent outlet, the other tidal
valve being at the bottom of aforesaid storage tank to prevent the tidal waters
interfering in any way with the working of the disposal works for the purification
of the sewage or waste waters. When the tide rises to the levels of the aforesaid
valves it closes them by reason of the pressure of the tides and allows the purified
waste waters or sewage to overflow the before mentioned weir into the storage tank
during the time of high water. As the tide recedes the valves open the effluent
then runs out at its normal level and the storage tank empties itself by means of
its tidal valves at its bottom.
I claim by the aforesaid combination that I can purify sewage or foul or waste-
waters by chemical or other means at all states of the tides without backing the
sewage into the sewers and that by reason of not altering the levels of the sewers I
can dispense with pumping whenever the invert of the sewage outlet is not lower
than eight feet below high water spring tides.
I further claim that by this combination I lose no fall in the precipitation or
disposal works but that the sewage enters the works at the same level as it
runs out, and that purification takes place without cessation at all states of the
tide.

I, EDWARD WILLIAM IVES, of 2 Strand, Derby, in the County of Derby,
Civil Engineer, do hereby declare the nature of this invention and in what manner
the same is to be performed to be particularly described and ascertained in and
by the following statement :-
The object of my invention is to purify foul or waste waters or sewage at all
states of the tides, without letting the tidal waters back the sewage or waste waters
or sewage gases into the sewers, and for this purpose I combine what is known as
an upward flow precipitating tank with a storage tank, the latter having an effluent
overflow weir together with two tidal valves and an effluent outlet well, one of the

valves it closes them by reason of the pressure of the tides and allows the purified
waste waters or sewage to overflow the before mentioned weir into the storage tank
during the time of high water. As the tide recedes the valves open, the effluent
then runs out at its normal level, and the storage tank empties itself by means
of its tidal valves at its bottom.
I claim by the aforesaid combination that I can purify sewage or foul or waste
water by chemical or other means at all states of the tides without backing the
sewage into the sewers and that by reason of not altering the levels of the sewers,
I can dispense with pumping whenever the invert of the sewage outlet is not lower

out and that purification takes place without cessation at all states of the tide.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a plan and Figures 2, 3 and 4 are sections on the lines 2-2, 3-3
and 4-4, Figure 1, showing a complete apparatus embodying my improvements.
a is the inlet pipe, 6 the screening chamber, c the storm overflow from it, d the
mixing race and e the outlet from it to the precipitating tank f. g is the overflow.
These parts are of well known construction and form the subject of the prior
Patents No. 13411 of 1893, No. 789 of 1894, No. 16724 of 1894, No. 20744 of
1894 and No. 22545 of 1895.
A is the storage tank and j is a trough across it by which the sewage is conducted
from the overflow g to the valve k well and outlet m. When however the tide rises
sufficiently high in the well to close the valve k the sewage rises in the trough j
and flows over the tops of the pipes u into the storage tank / from which it escapes
at low water by the valve o. p is a penstock for closing the outlet m.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
:―
1. The combination of a depositing tank, an overflow from it, a tidal valve on
the overflow, a storage tank and a weir between the tanks at a higher level than
the bottom of the overflow.
2. The combination of a depositing tank, a storage tank and outlets from them
substantially as described and shown in the drawings.
